OpenStack Horizon: integration tests for plugins (part 2, CI)

It’s a small addition to my previous post. I don’t like to edit my previous posts. The only exception is when I have to fix some typos, spelling error, links, etc.

During the previous post, I described how to implement integration tests for the Horizon plugins, but I didn’t have enough time to implement and verify CI for it. It’s time to fix this.

We’ve got really awesome CI in the OpenStack. Zuul works great for OpenStack needs and allows to configure cross-project jobs. A big thank you to our Infra team for the help during CI setup.

We’ve got horizon-integration-tests job for Horizon itself. It means that everything you need is to extend it and add few config options.

Here is an example from this patch:

- job:
    name: vitrage-dashboard-integration-tests
    parent: horizon-integration-tests
    required-projects:
      - name: openstack/horizon
      - name: openstack/vitrage
      - name: openstack/python-vitrageclient
      - name: openstack/vitrage-dashboard
    roles:
      - zuul: openstack-infra/devstack
      - zuul: openstack/horizon
    irrelevant-files:
      - ^.*\.rst$
      - ^doc/.*$
      - ^releasenotes/.*$
    vars:
      devstack_plugins:
        vitrage: https://git.openstack.org/openstack/vitrage
        vitrage-dashboard: https://git.openstack.org/openstack/vitrage-dashboard
      devstack_services:
        horizon: true
      tox_envlist: integration

I’ll describe you the most important parts.

parent: horizon-integration-tests - you need to make your job as a child of the existing one, to not duplicate code and playbooks.

required-projects - just add your project and client here to the list. It’s a requirement on how our CI works. It lets Zuul clone repos before Devstack starts. Cloning repositories during Devstack setup is not allowed.

roles - devstack and horizon needed here to be configured explicitly. I really need to check if everything works without this section.

devstack_plugins and devstack_services - here you can configure your. plugins and enable or disable some services from the Devstack default configuration.
